Abstract: Moving bed biofilm reactor (MBBR) using porous carrier plastic material, Polyurethane (DHY-1) which has high porosity 92% -96%, has been researched and applied in many water treatment systems. The advantage of the material is that it has high surface area of about 6,000-12,000m2/m3 thereby increasing the density of biomass. In this research, they were tried to treat ammonium nitrogen (N-NH4+) in the ground water. It was found that the treatment efficiency was more than 90% with N-NH4+ concentration of 10-12mg/l. Different densities of carrier materials as well as different influent flow rates have significant impacts on the removal efficiency. The study showed that treatment capacity decreased with high influent flow rate while increased with high density of carrier materials.
